1Reduced bone mineral density and altered bone turnover markers in patients with non-cirrhotic chronic hepatitis B or C infection显示文摘AIM: Previous studies suggest that loss of bone mineral density (BMD) frequently occurs in patients with chronic viral liver disease, presenting with histologically proven liver cirrhosis. However, little is known about the occurrence of bone disease in non-cirrhotic patients with chronic hepatitis B or C. Therefore, it was the aim of this study to evaluate this particular population for BMD and bone turnover markers.METHODS: Biochemical markers of bone turnover and BMD were measured in 43 consecutive patients with HCV (n = 30)or HBV (n = 13) infection without histological evidence for liver cirrhosis. Mean age was 49 years (range 26-77 years). BMD was measured by dual X-ray absorptiometry in the femoral neck (FN) and the lumbar spine (LS) region. In addition, bone metabolism markers were measured.RESULTS: BMD was lowered in 25 (58%) of the patients with chronic hepatitis B or C (FN: 0.76 (0.53-0.99); LS:0.96 (0.62-1.23) g/cm2). Eight (32%) osteopenic patients were diagnosed with osteoporosis. Bone-specific alkaline phosphatase (P = 0.005) and intact parathyroid hormone (iPTH) (P = 0.001) were significantly elevated in the more advanced stages of fibrosis. Mean 7-score value was lower in patients with chronic hepatitis C as compared to patients suffering from chronic hepatitis B; however, the difference was not statistically significant (P = 0.09).CONCLUSION: There was a significantly reduced BMD in non-cirrhotic patients with chronic hepatitis B or C infection. Alterations of bone metabolism already occurred in advanced liver fibrosis without cirrhosis. According to our results, these secondary effects of chronic viral hepatitis should be further investigated.Ingolf Schiefke Andreas Fach Marcus Wiedmann Andreas V.Aretin Eva Schenker Gudrun Borte Manfred Wiese Joachim Moessner 2005World Journal of Gastroenterology2005,11,12:23
2Contrast enhanced ultrasound of renal masses显示文摘Contrast enhanced ultrasound(CEUS) has gained clinical importance over the last years for the characterization of hepatic masses.Its role in extrahepatic indications has been investigated repeatedly but has been less comprehensively studied.Currently more than 50% of renal masses are incidentally diagnosed,mostly by B-mode ultrasound.The method of choice for characterization of renal lesions is contrast enhanced computed tomography(CECT).In the case of cystic lesions CECT refers to the Bosniak classification for cystic lesions to assess the risk of malignant behavior.The majority of masses are renal cell carcinoma,but the exact proportion is controversial.Disadvantages of CECT are a significant risk for patients with impaired renal function,allergic reactions and hyperthyroidism due to iodinated contrast agents.Several studies concerning CEUS for the characterization of both solid and cystic renal lesions have been published,but prospective multicenter studies are missing,the presented data being mainly descriptive.The aim of the this manuscript is to review the current literature for CEUS in renal masses,to summarize the available data and focus on possible concepts for studies in the future.Andre Ignee Bad Mergentheim Gudrun Schuessler Christoph Frank Dietrich 2010World Journal of Radiology2010,2,1:11
3持久性有机污染物(POPs)的监测:来自瑞典韦特恩湖的例子显示文摘位于瑞典南部的韦特恩湖是一个大的贫营养化湖泊,它具有高的水面与流域面积比率(大约为0.4)和60年的驻水时间。此湖结合了对大气POP污染的敏感性、对POPs影响的普通敏感性和较慢的浓度降低。提出了鱼体内PCBs和DDT从20世纪60年代一直到1996年的时间系列,以及韦特恩湖沉积物中TCDD的数据,并和其它大湖泊进行了比较。有关北极红点鲑(Salvelinus salvelinus)体内POPs的长期数据集显示每年PCBs有大约5%,DDT有13%的减少。这些速度和其它研究相一致。也讨论了营养物质及其生物效应,以及影响具有长驻水时间的贫营养化湖泊命运的因素。我们提出贫营养的干净湖泊是对于监测生物区中POPs的重要生态系统。MnsJ.Lindell Gudrun Bremle Ola Broberg Per Larsson 孙学飞 2001AMBIO-人类环境杂志2001,30,8:4
4Sensory reinnervation of free flaps in reconstruction of the breast and the upper and lower extremities显示文摘There is long-standing debate about sensate versus non-sensate free microvascular flaps among microsurgeons. The principle of connecting not only the vascular supply, but also sensitive nerves, in free tissue transfer is attractive. However, increased operating time and partial spontaneous innervation led to the common decision to restrict microsurgical tissue transfer to the vascular anastomosis and to leave the nerves 'untreated'. Nevertheless, in special cases such as breast reconstruction or extremity reconstruction, the question about sensory nerve coaptation of the flaps remains open. We present our experience with free microvascular tissue transfer for breast and extremity reconstruction and compare the data with previous literature and conclude that most free flap surgeries do not benefit from nerve coaptation.Nektarios Sinis Androniki Lamia Helml Gudrun Thomas Schoeller Frank Werdin 2012Neural Regeneration Research2012,7,29:4
5Cerebral venous thrombosis and heparin-induced thrombocytopenia in an 18-year old male with severe ulcerative colitis显示文摘The risk of thromboembolism is increased in inflammatory bowel disease and its symptoms may be overlooked. Furthermore, its treatment can be complex and is not without complications. We describe a case of an adolescent boy who developed a cerebral sinus venous thrombosis during a relapse of his ulcerative colitis and who, while on treatment with heparin, developed heparin-induced thrombocytopenia (HIT). The treatment was then switched to fondaparinux, a synthetic and selective inhibitor of activated factor .Gudrun Scheving Thorsteinsson Maria Magnussson Lena M Hallberg Nils Gunnar Wahlgren Fredrik Lindgren Petter Malmborg Thomas H Casswall 2008World Journal of Gastroenterology2008,14,28:4
6蒙古中部湖泊之谷沉积岩-玄武岩共存的渐新世地层:蒙古-奥地利合作项目回顾(英文)显示文摘Taatsiin Gol和Taatsiin Tsagaan Nuur地区的渐新世沉积序列具有重要的地层学意义:这里出露的三达河组和Loh组沉积含有多个化石层和玄武岩夹层。在蒙古-奥地利合作项目中,从研究区域的33个剖面/化石地点的85个化石层中采集了289种化石(11种腹足类、2种两栖类、9种爬行类和267种哺乳类)。本文提供了所有地点的完整哺乳动物清单,并结合大、小哺乳动物的新资料,对蒙古非正式的生物带A,B,C和C1进行了更新。40Ar/39Ar测年给出了至少两组玄武岩年龄:早渐新世玄武岩I组大约31.5Ma,晚渐新世玄武岩II组大约28Ma。它们可以用作渐新世哺乳动物地层学的年代校正点。从早渐新世至晚渐新世,哺乳动物群发生了显著的变化,包括晚渐新世种数的明显减少。这种趋势在肉齿类、食肉类和反刍类中最为突出。Gudrun DAXNER-HOCK Demchig BADAMGARAV Margarita ERBAJEVA 2010古脊椎动物学报2010,48,4:3
7过渡期内用临时限位栏代替永久限位栏以提高母猪福利研究概况显示文摘众所周知,限位栏是20世纪80年代兴起的一种适宜于工厂化养猪模式的养殖设备。在给人们带来生产管理上的便利以及效益的同时,限位栏也给母猪带来了巨大的伤害,因而也成为众多人士攻击的目标。有人说这是让母猪“坐水牢”,有人把它当成母猪的“隐形杀手”。早在2001年,欧盟就已向业界公布了使用限位栏禁令的概念,但是直到2013年,欧盟才正式出台对妊娠期母猪使用限位栏的新规定。但在我国动物福利标准中仍没有明确今后在母猪的饲养中禁止使用限位栏,限位栏是我国目前最能提高母猪生产效率的饲养方式。张振玲 Wackermannova Marie Goumon Sébastien Illmann Gudrun 2019猪业科学2019,36,2:2

9Serotonin type 3 receptor subunit gene polymorphisms associated with psychosomatic symptoms in irritable bowel syndrome:A multicenter retrospective study显示文摘BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with IBS.METHODS In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and Ireland.Depressive,anxiety,and somatization symptoms and sociodemographic characteristics were collected.Four functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive models.We also performed separate analyses for sex and IBS subtypes.SNP scores were calculated as the number of minor alleles of the SNPs above.The impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx assays.RESULTS Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in IBS.The potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant receptors.CONCLUSION We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with IBS.The SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS.Sabrina Berens Yuanjun Dong Nikola Fritz Jutta Walstab Mauro D'Amato Tenghao Zheng Verena Wahl Felix Boekstegers Justo Lorenzo Bermejo Cristina Martinez Stefanie Schmitteckert Egbert Clevers Felicitas Engel Annika Gauss Wolfgang Herzog Robin Spiller Miriam Goebel-Stengel Hubert Mönnikes Viola Andresen Frieling Thomas Jutta Keller Christian Pehl Christoph Stein-Thöringer Gerard Clarke Timothy G Dinan Eamonn M Quigley Gregory Sayuk Magnus Simrén Jonas Tesarz Gudrun Rappold Lukas van Oudenhove Rainer Schaefert Beate Niesler 2022World Journal of Gastroenterology2022,28,21:2

11Synthesis and thermoelectric properties of Rashba semiconductor BiTeBr with intensive texture显示文摘Bismuth tellurohalides with Rashba-type spin splitting exhibit unique Fermi surface topology and are developed as promising thermoelectric materials. However,BiTeBr, which belongs to this class of materials, is rarely investigated in terms of the thermoelectric transport properties. In the study, polycrystalline bulk BiTeBr with intensive texture was synthesized via spark plasma sintering(SPS). Additionally, its thermoelectric properties above room temperature were investigated along both the inplane and out-plane directions, and they exhibit strong anisotropy. Low sound velocity along two directions is found and contributes to its low lattice thermal conductivity. Polycrystalline BiTeBr exhibits relatively good thermoelectric performance along the in-plane direction,with a maximum dimensionless figure of merit(ZT) of 0.35 at 560 K. Further enhancements of ZT are expected by utilizing systematic optimization strategies.Jia-Zhan Xin Chen-Guang Fu Wu-Jun Shi Guo-Wei Li Gudrun Auffermann Yan-Peng Qi Tie-Jun Zhu Xin-Bing Zhao Claudia Felser 2018Rare Metals2018,37,4:2

16Scoring the collective effects of SNPs: association of minor alleles with complex traits in model organisms显示文摘It has long been assumed that most parts of a genome and most genetic variations or SNPs are non-functional with regard to reproductive fitness.However,the collective effects of SNPs have yet to be examined by experimental science.We here developed a novel approach to examine the relationship between traits and the total amount of SNPs in panels of genetic reference populations.We identified the minor alleles(MAs)in each panel and the MA content(MAC)that each inbred strain carried for a set of SNPs with genotypes determined in these panels.MAC was nearly linearly linked to quantitative variations in numerous traits in model organisms,including life span,tumor susceptibility,learning and memory,sensitivity to alcohol and anti-psychotic drugs,and two correlated traits poor reproductive fitness and strong immunity.These results suggest that the collective effects of SNPs are functional and do affect reproductive fitness.YUAN DeJian ZHU ZuoBin TAN XiaoHua LIANG Jie ZENG Chen ZHANG JieGen CHEN Jun MA Long DOGAN Ayca BROCKMANN Gudrun GOLDMANN Oliver MEDINA Eva RICE Amanda D.
